Mining[]
Jade Gemstone Ore
Gemstones can be mined in Crystal Hollows from their ores. Their ores generate in differently sized veins, in set locations within the Crystal Hollows and within random structures. Veins regenerate after some time, except when destroyed using Bob-omb.
Mining Gemstones will always give Rough tier of the item. ✧ Pristine grants a chance to drop a Flawed gemstone for each Rough gemstone harvested.
